Indexer Problems openjdk8 / Ubuntu 16 [message #1739237]

Hello,

this is my first post in this forum. I am an eclipse user for several years now and never experienced a problem like that. I switched to Ubuntu 16 recently and downloaded the latest Eclipse (Neon) CDT.
I build my projects with makefiles externally but use eclipse for developing.

Here is my problem. The indexer is very slow even though I have a powerful machine. It often hangs on 100% for a while and after it is finished, the member declaration of some classes is not found even though the header is detected correctly.

It looks like even though the indexer finds the header, it isnt indexing it correctly.

Can anybody help me with this problem? I work every day with eclipse and this is a real problem.

Kind regards,

Philipp

There is a glitch between GTK3 and Eclipse. These are workaround resolutions (use either):

1) Launch Eclipse with the parameter: --launcher.GTK_version 2
2) Set the environment variable to: export SWT_GTK3=0
3) Add "export SWT_GTK3=0" to your eclipse.ini file before the line "--launcher.appendVmargs"

Look at:

Eclipse Neon is very slow/hangs on fresh 16.04 install

Philipp, I hope that L.D. James has solved your problem with the GTK suggestion. GTK3 support in Neon is vastly improved, but there are a few cases to iron out. If this case is one of them I think it needs to be converted into a bug report so it can be improved.

Thank you very much for your reply. Using gtk2 instead of 3 actually improved eclipse a lot. While I was testing your solution, I found the real reason for the problems. If the headers of pcl1.7 are included in the paths and symbols, the described behaviour appears. It might result from a double include from pcl and ros-pcl, but I am not sure yet.
